DEVICE FOR ASSEMBLING PRINTED-PAPER STRIPS IN TRUE REGISTER.

Specification of Letters Patent.

Application filed November 25, 1907.

Patented March 17, 1908.

Serial No. 403,822.

T 0 all whom it may concern:

Be it known that 1, PAUL AsHELM, a subject of the Emperor of Germany,residing at Berlin, Germany, have invented certain new and usefulImprovements in Devices for Assembling Printed-Paper Strips in TrueRegister, of which the following is a full, clear, and exactspecification.

In producing pads with a printed face, the letters and numerals of whichshould exactly register, as in block-calendars, check books orticket-pads, generally, the printed sheet coming from the press in anendless band, has been cut into narrow strips, which are led overturning prongs, so as to bring the strips in line above each other, andto form a continuous strip from which the pads are out. A machine ofthis kind is described in my U. S. Patent No. $46,716.

It is evident that the print, in order to register on the stripsassembled above each other, must be applied to the sheet in the printingpress in a diagonal line, under an angle of exactly when the pads aresquare, and under a corresponding greater angle, when the pads are madelonger than their width.

It is difficult to find the angle for the distribution of the type whichanswers exactly to the desired length of the pads and irregularities inthe register of the letters and lines can be corrected only by thetedious work of shifting the type in the press, till the correctdiagonal position is found.

But irregularities in the register are also produced by a variation ofthe tension in the individual strips, which are run together into thepads through the turning prongs and by defective adjustment of theposition of these latter.

The present invention has for its object to facilitate the correction ofirregularities in the register of the printed lines, the dates,numerals, etc. and to do away with the slow and tedious shifting of thetype.

The new adjusting device is of such a nature, that it permits to set upthe type under the angle of 45 and even less for all lengths of padsfrom square to the longest rectangular shape and the registering isobtained in the easiest possible manner. To this end an adjustable levercarrying a tension roller is provided for each individual paper strip,acting upon the loop between the press and the turning prongs, and byvarying the length of this loop the register of all the strips 1sreadily adjusted.

In the accompanying drawing forming part of this specification the newdevice is' shown, Figure 1 being a diagrammatical side elevation and F2, a plan view. Figs. 3 and 4 illustrate modifications in the means tovary the distance of the tension rolls from 'the shaft forming thefulcrum of the levers.

hubs on one end are shifted upon said shaft i on which they can besecured in a desired position by set screws m. On the outer or free endof the levers or arms 1 guide rolls 7c are mounted revolubly on pinsprojecting laterally from the levers. Each guide roll extends crosswiseover one of the narrowstrips going to the turning prongs. In order tobring them all to the same level with these prongs, a cylinder at isprovided above the guide rolls is to which the strips g ascend more orless convergent lines, and from which they pass in parallel lines andpractically in one plane to the turning prongs. Here the strips arefolded rectangularly in the well known manner and run out assembled to athick continuous strip comprising the superposed individual strips 9from which the pads and calendars are cut. Should the print on the stripgin this assembled thiek strip not register conveniently it is onlynecessary to adjust the levers Z on the shaft 1' with the guide rolls 7ccorrespondingly to lengthen or to shorten the loop as the case mayrequire. This will. be easily understood from Fig. 1.

Fig. 3 shows a modified form of lever I, being composed of two partspivotally con nected and provided with a clamp screw to set them fast atany desired angle. .VVith levers of such construction the distance ofthe guide rolls 7t from the shaft 4/ can be va ried at will and in thisway the loops 9 can be lengthened or shortened as necessity requires.Moreover the arms can be turned and set fast on the shaft '5 in the samemanner as the arms Zin Fig. 1.

Fig. 4 shows another modified construction which permits to vary thedistance of the guide rolls from the shaft 1'. The arms Z are slidablymounted in sleeves 0 wherein they can be secured by set screws as shown.The bore in the sleeve 0 is at right angles to the eye or hub, shiftedon the shaft 1'.

Having thus described my invention, what I claim is:

1. In machines for assembling printed paper strips for block calendars,ticket pads and the like, a device for shifting theindi vidual stripsinto true register of the print, composed of guide rolls, one for eachstrip, of levers carrying said guide rolls of a shaft upon which saidlevers are fulrcumed, and of means to set the levers fast in theiradjusted position.

2. In machines for assembling printed paper strips for block-calendars,ticket pads and the like, cutters dividing the paper into a number ofstrips for the pad, and a device for shifting the individual strips intotrue register of the print arranged in front of said cutters, composedof 'guide rolls, one for'each strip, of levers carrying said guide rollsof a shaft upon which said levers are fulcrumed, and of means to set thelevers fast in their adjusted position, and of a guide roll and theturning prongs at a level therewith, substantially as described.

3. In machines for assembling printed paper strips for block-calendars,ticket pads, and the like, a device for shifting the individual stripsinto true register of the print, composed of guide rolls, one for eachstrip, of levers carrying said guide rolls, of a shaft upon which saidlevers are fulcrumed, means to vary the length of said levers and toadjust the distance of the guide rolls from the shaft, and of means toset the levers fast in their adjusted position.

In testimony whereof I affiX my signature.

PAUL ASHELM. In the presence of WOLDEMAR HAUPT, HENRY HAsPER.
